Didn't you think to use a 'dumbphone' instead of 'smartphone' for a moment in order to remove a PIN request at all? Anyway, IMHO it's rather a Treo problem.

In my Pocket Loox T830 (with Windows Mobile) PIN can be entered either via the touchscreen or the keyboard. The keyboard, however, works in a specific mode. E.g. non-digital input is not allowed but the keyboard is not switched to the numeric mode - I must press the FN key before pressing any numeric key, otherwise no input at all.

Anyway, smartphones aren't smart at all when they have to deal with sophisticated callback SIM applications. E.g. my Loox with UM+ accepts calling *137* codes only whereas old Siemens C35 works perfectly
